Description

Note

In the Open vSwitch Database (OVSDB) schema for physical devices, the logical switch table stores information about the Layer 2 broadcast domain that you configured in a VMware NSX or Contrail environment. In the NSX environment, the Layer 2 broadcast domain is known as a logical switch, while in the Contrail environment, the domain is known as a virtual network.

In the context of the show ovsdb logical-switch command, the term logical switch refers to the logical switch or virtual network that was configured in the NSX or Contrail environments, respectively, and the corresponding configuration that was pushed to the OVSDB schema.

Display information about logical switches and the corresponding Virtual Extensible LANs (VXLANs), which were configured on the Juniper Networks device.

In the command output, each logical switch is identified by a universally unique identifier (UUID), which in the context of this command, is also known as a logical switch name.

The show ovsdb logical-switch command displays the state of the logical switch (Flags), which can be one of the following:

Created by ControllerA logical switch is configured. However, a corresponding VXLAN is not yet configured. In this state, the logical switch and corresponding VXLAN are not yet operational.
Created by L2ALDA VXLAN is configured. However, a corresponding logical switch is not yet configured. In this state, the logical switch and corresponding VXLAN are not yet operational.
Created by bothA logical switch and a corresponding VXLAN are configured. In this state, the logical switch and corresponding VXLAN are operational.
Tunnel key mismatchThe VNIs specified in the logical switch and corresponding VXLAN configurations do not match. In this state, the logical switch and corresponding VXLAN are not yet operational.
